This patent application claims priority to U.S. Provisional Patent Application 60/333,297 filed Nov. 19, 2001.
1. Field of the Invention
The invention relates to golf clubs. More particularly the invention related to a set of golf heads attachable to at least one shaft of variable lengths.
2. Prior Art
The invention is best understood is a single club which is extendable, which has a gripping end, an extending end, which is extendable in at least one of many ways. One way the arm extends is by having set incremental extensions which are locked in place by way of a button type locking mechanism. A second way that the arm is extendable is by having a friction lock which may be engaged or disengaged by pushing on a button which either engages or disengages a lever pushing against the arm.
Another way that the arm is extendable is by screwing or unscrewing an extension from the gripping portion of the arm.
Regardless of which method is used, there is an indicating means which shows, utilizing color or number coding the appropriate extension for a specific club head which head has a corresponding number or color coded or some other form of coding.
In this way, quick reference can be made to the club head and the extension of the club in order to determine that the correct club is in place and that the arm is properly extended.
In some of the embodiments there is additionally a flexing portion of the club which is one or more flexing ends of the club, which flexing ends allow the club to flex and bend in a fashion mimicking that of clubs that do not have extending means. In this way the clubs may be made of multiple materials along their length in order to allow them to function optimally while being extendable. Along the lengths of the club there are tapered and not tapered portions from the top to the club head.
Another mechanism of providing a changeable length would be to have each of the club heads have a different length ankle portion. In this way the club itself would not have to extend, but there would be different length ankles on each of the club heads.
In one embodiment there are two separate clubs each having a different length and no extendability is used, but instead a plurality of golf heads for the first club, which is the length of a wood in the set, and the second club which is an iron length. The extendable club may be a part of one or both of the two clubs in this set as described herein one may be extendable, the other one could be of a fixed length.
There is also a special head for using as a putter in this embodiment. In this way a putter may be used both as a short putter or a long putter according to the use desired by the player and a heavier or lighter putting head may be utilized in order to maximize the club head weight for play on different thicknesses of grass or in different moisture conditions.
In addition, there is an alignment means and a locking means which serve to allow for proper alignment of the club heads onto the attachment end of the club shaft. Except by releasing a locking means by action specifically designed to remove the club head initiated by the user that the club head can not be separated so as to prevent the club heads from coming loose when in use.
In the preferred embodiment the locking means is in the form of a spring loaded lock mechanism which is colored green when the club head is locked in place so that the user will know visually that the club head is properly locked in place before attempting to use the club or swing the club in order to prevent any possibility that the head would come separated from the club during play.
Also shown, is a shoulder and stand mechanism for carrying the club and the belt over the users shoulder when moving from one location to the next.
It is therefore another object of the invention to provide a belt means which may be self supporting so that the user may clip or insert into pocket all of the club heads except for the one in use at a particular time and either wear the belt when traveling or set the belt down on its self supporting tri-pod when slinging a club.
It is therefore one object of the invention to provide a lighter and more transportable set of golf clubs, and a set of golf clubs which can be used by someone who would wish to walk a course and not drive a course without adding a great deal of additional weight.
It is another object of the invention to provide a club set of the type mentioned which is ergonomically designed to be carried by the user and also designed that in order to be supported when set down.
It is also one object of the invention to provide one club with the gripping end, an extending end, a vending end, an attaching end, a locking means, a marking means for the extension, a locking means for the extension and a locking means for the attachment of a plurality of golf heads corresponding to different golf heads which the user might desire in a particular setting.
It is also an object of the invention to provide such a mechanism in a golf club set which also includes socks in order to prevent contamination by dirt, sand or moisture.
These and other objects and advantages of the invention will become better understood hereinafter from a consideration of the specification with reference to the accompanying drawings forming part thereof, and in which like numeral correspond to parts throughout the several views of the invention.
For a further understanding of the nature and objects of the present invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings in which like parts are given like reference numerals and wherein:
As shown in
In some embodiments, described below, a single club length for the gripping end 30 is possible. In this embodiment, an adjustment is possible in the club length at a non-tapering section 9, utilizing spring released bearings 16 within a bearing support cylinder 25 which bearings 16 can fix the location of the gripping end 30 on the second tapering end 13 by fitting fixedly into first holes 17 defined by the non-tapering portion 48 of the second tapering end 13. It would be possible to replace these holes 17 with threads (also a form of holes) and to replace the bearings 16 with threads within the cylinder 25 which cooperated with the threads to allow for adjustment or to combine these two methods. In this case the spring has an end attached to the cylinder 25 and is fixed on the other end to the gripping end so that the cylinder 25 can move against the spring 27 to allow the bearings 16 to be locked in place or released into release holes 26 defined by the cylinder 25.
Threads can be seen used in this manner in
It is to be noted that as the handle lengthens, it flexes more and this allows for users, as it goes from a child club length to a grown up club length, to get used to a gradually increase in the amount of flex in the club.
The fine adjustment might be preferably at the attachment handle 10, and in
To allow the angle and length of the clubs to be varied, there may be different attachment handles 10 having different lengths and angles of attachment to the club striking surface 49 as described in more detail below in order to keep the striking surfaces 49 properly aligned.
In this embodiment, the club heads 14 are interchangeable, utilizing spring released bearings 16 a within a bearing support cylinder 25 a which bearings 16 a can fix the location of the club head 14 on the first tapering end 13 by fitting bearings 16 a releasably into first holes 17 a defined by the end of the second tapering end 13. It would be possible to replace these holes 17 a with threads (also a form of holes) and to replace the bearings 16 a with threads as shown in
To improve alignment, there is an extension 29 off of the attachment handle 10 which fits tightly within slot 19 defined in the bearing support cylinder 25 a.
At the end 74 of the non tapering section 9 is a bearing support cylinder 25 which defines a space 26, which is typically a groove traveling around the inner circumference of the cylinder 25. Within this cylinder 25 are typically two bearings 16 which fit within grooves defined by the cylinder 25. Typically, the bearing may rotate.
This bearing may be released from pressing on the non tapering section 9, which is the non-tapered portion of second tapering end 13, by pulling the bearing support cylinder 25 against the spring 27 until the bearing 16 can fit within the space 6.
The method of the movement of the bearing holding cylinder, the bearing support cylinder the bearing support cylinder release hole is a mechanism which is known in the prior art of holding mechanisms but is not utilized for the purposes described herein.
This way, the at least first set of holes which are at one distance from one another and at least one second set of holes which are at a similar length from one another but separated by an extended length from the first set of holes is provided in order to provide for club lengths to easily be adjusted for wood or easily be adjusted for the irons.
A similar mechanism is provided at the end of the second taper for attaching a club. In this second case there is a specific alignment means which in this case is a slot 19 which receives an extension 29, attached to the club head 14. In this case there is a groove 28 a which may go all the way around the club head to receive the bearing 16 a (in this case there is an first bearing and a second bearing on the other side of the club head groove 28 which groove 28 may pass completely around the attachment handle 10 which is also definable as the club head shaft.
The bearing may fit within one of the holes 17 depending on how far the first taper 11 is inserted with section 9 in order to adjust the length of the club to correspond to the necessary length for a particular club head 14.
To increase the strength of the unit and to be able to withstand greater force there are, as shown in
To allow for a single club to be used for vastly different sized club lengths (such as a father and son club), there may be, as shown in
For a single user, typically the attachment handle could be varied enough so that the club length, at most would only have to be locked in three positions, the three positions being for irons, one for woods, and potentially a different one for a putter.
As shown in
Another way to accomplish this shown in
In the embodiment shown in
These embodiments, instead of extending clubs, has at least two separate clubs and in this example shown in
In an alternative embodiment as shown in
One embodiment the invention comprises a gripping end 30 which has a taper to the shaft 34 so that the shaft 34 can flex.
If the first taper and attachment handle are long enough, the may also taper so as to be able to flex similarly to an existing club. The tapers may be controlled to make the flex desired.
One improvement is to provide between the gripping end 30 and striking surface 49 an extension means 35 of the type described above comprised of items 25, 16 and 13, by way of example.
While the extension means 35 can have several different varieties, one example shown in
The holes 17 may spiral around the outer surface of the tapering end 13. One purpose of having them spiral would be in order to ensure that the correct club head is used. In such an embodiment the club heads would lock in along an axis so that only the correct club would line up correctly depending on how far out or how far turned is one shafts relative to another.
The lever arm 56 rocking arm so that pushing on button 45 (as opposed to a pull button) compresses the rear end 56 a of the arm 56 rotates the arm 56 around a pivot 58 so as to disengage the locking arm 63 from the hole 17. While referred to as a hold, it may be easily referred to as an indention.
Markings 32 are displayed on the end 13 as it is extended from the inside of the non-tapering section 9 a so that the user will know which club head, heads 14–14 e in this example, to use based on the amount of extension. Presumably these markings would be number coded for irons from 2 to 9, and also for pitching(P) and sand wedges(S), and similarly could be marked for woods 1 through 5. Other clubs are available, but those are the club numbers that would be found with a standard club set.
As can be seen by reference to
In this case the fictional lever means is comprised of what can best be seen by reference to
Here it is a fictional brake 57, which is mounted onto one end of a lever arm 56 with the far end 59 of the lever arm being held by expanding spring 61 in frictional contact with the top surface 64 of the second non tapering section 9 b. This may or may not be assisted by way of a locking arm 63 fitting into a hole 17 in the second non-tapering section 9 b.
The brake 57 pivots in response to pressure on the button 45 on top of the lever arm 56 by the user pushing down on the button 45 to release the brake and adjust the club.
As can be seen by reference to
The graduated markings 32 function to allow the user to know which hole 17 is being used depending on which one is displayed in a method discussed in more detail below.
While a single extension of this type is adequate in order to allow for the club to function, there are reasons related to design where two separate adjusting ends might be desirable. The primary reason for this is because there is one gross adjustment which is important for going from the length of an iron to the length of a wood, and then there are more fine adjustments for the different size irons and the different size woods in a standard golf set. Also, more than one extension means of the type shown may be present.
In another embodiment, instead of, or in addition to, having the length of the club change, the attachment handle 10 on each club head 14 is a different length.
In this way, depending on which club head is selected, the length of that club head is automatically changed.
This allows the entire club to taper all the way down to the point in which the club head is attached to allow for greater flexibility in the shaft.
There may also be a secondary pen 22 holding the club by way of a club locking bracket 23 so that when a club is twisted in place and aligned it can not be unaligned without the user consciencely moving the secondary pen 22 which may be put in place over the insertion location by which twisting allows for the alignment window to be inspected.
As can best be seen in
As set forth above, the combined device is for playing golf requiring at least two clubs with a first length and a second length comprising. In this case, the first length and second length are taken care of by having a club which changes size or by having heads with different length shafts attached.
In this embodiment, there are multiple club heads comprising at least one first club head comprising:
The flat surface has a length and a width and a thickness and the length is at least one half inch wide. The width is at least one half inch wide. However, the length is preferably at least one inch wide and the width is at least one inch wide to provide sufficient bracing as described below.
The thickness of this flat section is less than ½ inch.
The flat surface 75 as shown in
The grasping means further comprises an extension 80 releasably insertable into the flat surface opening 79. The grasping means further comprises a top wall 90 and a bottom wall 91 separated by a slot 89 wherein slot defines a slot height which height is approximately equal to the thickness of the flat surface 75 so that the flat surface is tightly held rotationally and otherwise. The opening 79 being in the center of the flat surface and the extension being the same size and shape as the opening 79 also helps to tightly hold the flat surface and therefore the club.
The top wall and bottom wall contact at least a portion of the top face and bottom face of the flat surface, as indicated above, at least ½ square inch of each surface.
The flat surface 75 has a first end 86 insertable into the opening between the top wall 90 and bottom 91 wall and aback 75 c which is attached to handle 10 and a middle between the first end 86 and the back 75 c. The middle is pivoted about a fulcrum 81 which fulcrum is attached to the bottom wall 91. The top wall 90 defines an opening. This top wall opening shown in
In the preferred embodiment, this invention comprises at least one second one club head comprising:
Typically, the first club head connection angle is different from the second club head connection angle.
As shown in
The shape is designed to allow for easy insertion and prevent release.
Because many varying and different embodiments may be made within the scope of the inventive concept herein taught and because many modifications may be made in the embodiment(s) herein detailed in accordance with the descriptive requirements of the law, it is to be understood that the details herein are to be interpreted as illustrative and not in a limiting sense.
